Interface Summary
Interface	Description
AsyncCloseable	An object that may hold resources until it is closed.
Listenable<T>	An interface that accepts item change listeners.
ListenableAsyncCloseable	A variant of `AsyncCloseable` which allows a user to check whether the object is closed or to get notified when closed.
ReleasableHolder<T>	A holder of releasable resource `T`.
SafeCloseable	An `AutoCloseable` whose `SafeCloseable.close()` method does not throw an exception.
Sampler<T>	Sampler is responsible for deciding if a particular trace should be "sampled", i.e. whether the overhead of tracing will occur and/or if a trace will be reported to the collection tier.
Ticker	A time source; returns a time value representing the number of nanoseconds elapsed since some fixed but arbitrary point in time.
Unwrappable	Provides a way to unwrap an object in decorator pattern, similar to down-casting in an inheritance pattern.

Class Summary
Class	Description
AbstractListenable<T>	A skeletal `Listenable` implementation.
AbstractOption<T>	A configuration option.
AbstractOptions	A set of configuration options and their respective values.
AbstractOptionValue<O extends AbstractOption<V>,V>	A holder of a value of an `AbstractOption`.
AbstractUnwrappable<T extends Unwrappable>	Skeletal `Unwrappable` implementation.
AppRootFinder	A utility that looks for the `Path` to the JAR, WAR or directory where a `Class` is located at.
AsyncCloseableSupport	Provides support for implementing `AsyncCloseable` or `ListenableAsyncCloseable`.
CompletionActions	Provides the common actions that are useful when handling a `CompletionStage`.
EventLoopCheckingFuture<T>	A `CompletableFuture` that warns the user if they call a method that blocks the event loop.
EventLoopGroups	Provides methods that are useful for creating an `EventLoopGroup`.
EventLoopThreadFactory	Deprecated Use `ThreadFactories.newEventLoopThreadFactory(String, boolean)` or `ThreadFactories.builder(String)`.
Exceptions	Provides methods that are useful for handling exceptions.
Functions	Utility methods related with function composition.
InetAddressPredicates	A utility class which provides factory methods in order to easily create a `Predicate` of an `InetAddress`.
LruMap<T,U>	LRU (Least Recently Used) cache `Map`.
NativeLibraries	Deprecated Use `Flags` instead.
StartStopSupport<T,U,V,L>	Provides asynchronous start-stop life cycle support.
SystemInfo	Provides utilities for accessing the information about the current system and process.
TextFormatter	A utility class to format things as a `String` with ease.
ThreadFactories	Provides a builder for `ThreadFactory`.
ThreadFactoryBuilder	Builds a new `ThreadFactory`.
UnmodifiableFuture<T>	A `CompletableFuture` which prevents the caller from completing it.
Version	Retrieves the version information of available Armeria artifacts.
